squeak-vm 1:3.9.8-3ubuntu3 (i386 binary) in ubuntu lucid

 Squeak is an open, highly-portable Smalltalk-80 implementation whose
 virtual machine is written entirely in Smalltalk, making it easy to
 debug, analyze, and change. To achieve practical performance, a
 translator produces an equivalent C program whose performance is
 comparable to commercial Smalltalks.
 .
 This is the virtual machine distributed by Ian Piumarta, author of
 the original port of the VM to Unix.
